The object of this invent-ion 'isto provide a simple and inexpensivedevice which may be easily applied to or removed from the windshield ofan automobile or other vehicle and by its use provide a clear visionarea notwithstanding stormy climatic conditions. The invention isillustratedin the accomanying drawing and will be hereinafter fully setforth.

In the drawing: 7 Figure 1 is a perspective view SllOWlIlg oneapplication of my device,

Fig. 2 is an enlarged central vertical section, Fig. 3 is a frontelevation showing a different application of the invention, and

v Fig. 4 is an enlarged detail section on the line H of Fig. 2.

In the drawing, the reference numeral 1 indicates a portion of anautomobile, and 2 the usual windshield provided thereon. My clear visiondevice comprises a rigid frame 3 which is preferably rectangular and maybe constructed of wood or other material. The rear side of this frame iscovered with felt, rubber or some similar material, indicated at 4,whereby light pressure of the same against a windshield will effect anair-tight joint therewith. are lugs 5 having grooves 6 extending acrosstheir front faces and preferably convex on their outer sides. One ofthese lugs is provided on each member of the frame and the purposethereof will presently appear. Secured to the inner surface of eachmember of the frame 3 is'a transparent sheet of material which ispreferably celluloid or the I like for the sake of economy andavoidanceof weight, but it will be understood: that these sheets may be of glassor any other transparent material. As shown clearly in Figs. 1 and 2,the top and bottom sheets 7 converge forwardly while the end sheets 8are disposed in vertical parallel planes. The meeting edges of theseveral sheets are covered with any light material, indicated at 9, andin the angles defined by the meeting edges are fillings 10 of wax orsimilar material whereby an air-tight joint will be effected. The bind-59 ing strip 9 may be sewed or otherwise at- On the outer side of theframe 3 tached to the sheets 7 and Sand'light rivets will preferably beemployed for this purpose. The front 'edges'ofthe top and bottom sheetsare spaced apart to define a narrow slot or sight opening 11, andinorderto maintain the form of this opening against distortion,

a reinforcing rim 12 of metal'is preferably provided around the same, asshown clearly in Figs. 2 and 3. In applying thedevice to the. vehicle,straps, such as shown at 13, are disposed across the frame of the deviceand engaged with the lugs or projections 5 so that the device is heldclosely to the wind-' shield but may be readily shifted to meet theconvenience or desires of the chauffeur. In Figs. 1' and 2, the straps13 are shown extending horizontally across the windshield and engagedwith thelugs or projecti-ons 5' on the top and bottom of the frame. Withthis arrangement, the ends ofthe straps'are fastened in any convenientor preferred manner to the frame'ofi the vehicle body but they may,fc fcourse, be fastened to the windshield frame. Vilith some models ofautomobiles, its is not feasible to dispose the retaining 7 strapshorizontally and in such case the straps may. be disposed vertically, asshown at 143111FlgJ3. In this arrangement, the straps, of course, engagethe lugs on the end members of the frame 3. The retaining. straps may beequipped with books, as indicated at 15, or otherwise equipped so as tobe engaged with the windshield, the windshield frame or projections onthe vehicle body.

It will be understoodthat the device is to be so disposed upon thewindshield that the sight opening or slot 11 will be located directly infront of the eyes of the chauffeur. Inasmuch as the frame is heldagainst the windshield with an air-tight oint, there will be nocirculation of air through the device and any air which enters throughthe slot 11 when the vehicle isin motion will be merely trapped thereinand somewhat compressed so that snow or rain cannot be drawn through thesightopening which will always remain clear so that the chauffeur willhave an unobstructed view of the road ahead. Actual tests of this devicehave demonstrated that in foggy or inclement weather the vehicle may besafely driven at a high speed as the chauffeurs view is clear and notbedimmed by any deposits. It is, of course, possible that there may besome slight deposits upon the top sheet 7 of the device but the bottomsheet 7 will always be clear and the side or end sheets being disposedvertically will, of course, tend to shed any snow or rain which mighttend to collect thereon. The retaining straps firmly hold the clearvision device to the windshield while at the same time the device may bereadily shifted in its position as circumstances may demand. The deviceembodying the invention is very light and may be produced at anexceedingly low cost and may be applied to any windshield withoutrequiring the services of a skilled mechanic or the use of anyparticular tools. l/Vhile the device is intended more particularly foruse upon motor vehicles it may, of

course, be used advantageously upon motor boats, aeroplanes or any othervehicles which are intended to be driven at high speed.

Having thus described the invention, I claim:

A clear vision device for vehicles compris ing a rigid frame providedwith projections on its front side at its ends and at its top andbottom, said projections having convex v front surfaces and havinggrooves across said surfaces, a transparent shell secured .to andprojecting forwardly from the frame and having a narrow sight opening atits front end, said frame projecting outwardly about the margins of therear end of the shell and the projections disposed outside the shell,and attaching straps secured at their ends and having their intermediateportions passing over the projections on the frame and seating in thegrooves therein whereby to hold the device to a windshield.

In testimony whereof I aflix my signature.
